Drensky Technologies provides numerous quality, specially-designed batteries from the CSB and Royal Delkor ranges. These batteries have proven to be especially reliable in the Uninterruptible Power Supplies (UPS) industry for many years. Our experts will assess the application and necessary run-time requirements of your systems in order to provide you with the correct battery solution for your needs.
Royal Delkor Batteries
Royal Delkor batteries use specially-alloyed calcium-lead, which leads to extremely low levels of electrolyte decrease. This means that there is no need to supplement distilled water if the charging system remains error free and special liquid-gas separators keep the electrolyte inside. An electrolyte is any substance containing free ions that behaves as an electrically conductive medium. These separators are also used between the positive and negative plates of a lead acid battery to prevent a short circuit through physical contact. No filler caps are required and there is, therefore, no electrolyte contamination, overwatering or damage in use.
The unique, wrought lead-calcium grid design means less internal corrosion and efficient current conductivity for more power and longer life. It also limits gassing and resists overcharge, heat and thermal runaway.
The Royal Calcium Battery
The Royal Calcium Battery is a general purpose, semi-sealed battery with a design life of up to 3 to 5 years in stand-by service.
• Complete protection against reduction of sulphuric acid.
• Prevention of electrolyte losses by collecting and returning liquid to the reservoir.
• Consistent starting performance.
• High durability achieved by adoption of special wrought lead calcium grids.
• A low-resistance envelope separator which prevents short circuiting.
CSB Batteries are specially designed for high efficient discharge application. Their characteristics are high energy density, small footprint and high discharge efficiency. They can be used for more than 260 cycles at 100% discharge in cycle service and for up to 5 years in standby service
